Gasoline engine



.To all whom it may concern:

Be it known that .l, ALco'r l lVnsriaiNo, a citizen of the Dominion ofCanada, residing at Brownies, in the county of Moose Jaw and Province ofSaskatcheivan,'@an-' ada, have invented certain new and usefulimprovements in Gasoline Engines, of which the following is aspecification.

The present invention relates to improvements in gasoline engines, theprincipal objects being to provide an engine of the character described,which will have a maximum amount of power, less piston vibration, and

1 be simple and compact in construction.

With these and (ithe'r objects in view, the invention consists in theconstruction, combination, and arrangement of parts, as will behereinafter fully described, illustrated in the accompanying drawing andpointed out in the claims hereunto appended.

The drawing is a top plan view illustrating part of the cylinder headsin section.

lieferring to the drawing, like numerals designate like parts in thedrawin The numeral 1' indicates the base, having substantially mountedthereon a pair of cylinders 2 and 3. Pistons l, 5, 6' and 7 are slidablymounted in the cylinders 2 and 3, each pair of pistons being connectedby a rod 8. Each pair of pistons are substantially connected by bracketmembers 9, as

indicated diagrammatically.

The cylinders Will be preferably cast intact, having slotted openings 10on the interior side and registering opposite each other to allow thereciprocation of the bracket members 9 therein. These bracket members 9are secured to the reciprocatory piston rod 11, slidably mounted inbearings 12 and 13. On the outer end of this piston rod 11, isconnection rod 14;, suitably mounted on and functioned to actuate thecrank 15 configurated on the transverse crank shaft 16, which shaft isjournalled in bearings 17 and 18. On the outer ends of the transversecrank shaft 16 are mounted fly Wheels 19 and 20, functioned to addimpetus to the rotation of the said transverse crank shaft. Bevelpinions 21 and 22, mount-ed on the transverse crank shaft 16, drivebevel pinions 23 and 24: mounted on the vertical shafts 25 and 26. Thesevertical shafts 25 and 26 are journalled in bearings 27 suitablypositioned on the base 1. Bevel pinions 28 and 29 mounted on the ends ofthe vertical shafts 25 and 26, drive bevel pinions 30 and 31, mounted ontransverse sha' the intake and exhaust valves 4-1 and 42 pcll F5sitioned in the ends of the cylinders. Spark plugs are suitably'mountedon the cylinders for ignition.

As indicated diagrammatically, that would be behind piston is about tobe exploded. The spent in front of piston 5 is about to be expelledthrough the open exhaust valve Gas from the manifold is entering intakevalve 4-1 into the cylinder before piston 6, While the gasin front ofpiston 7 is about to be compressed.

The explosion of the gas before piston l forces the combined pistonforward. The actuating of the cams opens exhaustvalve 42 before piston55, allowing the escape of the spent gas to a suitable exhaust.Simultaneously, intake valve ll opens and the gas enters into thechamber before piston 6. The

gas in the chamber before piston Y is thus compressed.

Une the return stroke the compressed gas before piston 7 is firedforcing the combined pistons back. The gas in the chamber before piston6 is compressed. The actusting cams automatically close the exl aust andopen the intake valve into the chamber before piston 5. The exhaustvalve before piston l is opened, and the spent gas e2;- pelled. Eachsuccessive stroke causes reciprocation of the piston rod 11, which inturn, imparts rotation of the fly wheels.

From the foregoing, it is thought that the construction of my inventionWill be clearly understood, and, therefore, a more extended explanationhas been omitted.

What- I claim as new is:

1. In a gasoline engine of the character stated, a pair of cylinderscast integral with registering slots adjacent each other. pistons inpairs in each cylinder, bracket members extended through said slots andconnected to said pistons, a piston rod connected with said bracketmembers, and a rod connected with the crank shaft for actuating the saidpiston rod.

.2. In a gasoline engine of the character i stated, a pair of cylinderscast integral with ing' formed with hearings through which "nected tosaid pistons" a piston rod connect registering slots adjacent eachother, pissaid piston rod reciprocatesx- 10 tons in pairs in eachcylinder, bracket mem-. In testimony whereof I afiix my signature bersextended through said slots and 0011- in the presence of two witnesses.
